High-impact PCR PC/ABS material and preparation method thereof

The invention discloses a high-impact PCR (Polymerase Chain Reaction) PC (Polycarbonate)/ABS (Acrylonitrile Butadiene Styrene) material and a preparation method thereof, and the high-impact PCR PC/ABS material is prepared from the following raw materials in percentage by weight: 50 to 87.5 percent of PCR-PC, 10 to 47.5 percent of PCR-ABS, 0.5 to 2 percent of long-chain branched polymer and 2 to 5 percent of MBS. According to the invention, by introducing the long-branched-chain structure polymer, compounding with the terpolymer MBS and forming a bridging effect with the PCR PC/ABS polymer, the molecular weight of the PCR polymer can be improved, the impact strength and melt strength of the PCR PC/ABS polymer can be remarkably enhanced, the defects of insufficient performance and low use content of the PCRPC/ABS material are overcome, and the high-content proportional application of the PCR PC/ABS material is promoted. 本发明公开一种高冲击PCR PC/ABS材料及其制备方法，按重量百分比计，原料包括PCR-PC：50～87.5％，PCR-ABS：10～47.5％,长支链聚合物：0.5～2％，以及MB
